The purpose of this thesis is to showcase how stress represents one of the main triggers of wor-kplace bullying. Be it psychological, moral or physical workplace bullying, it is becoming more frequent both in the world and in the Republic of Croatia. Exactly this kind of abuse is now know as 'mobbing'. The extent of mobbing in Croatia is still unknown, especially in civil services. While individual foreign studies warn that civil services are at a high risk of mobbing, the low number of Croatian studies fails to show the whole picture even thou that risk is exceptionally high in Croatia. The model of mobbing, or 'bossing' in civil services will differ by circumstances, goals and characteristics of the aggressor and victim, and by the patterns and manifestations from the 'standard' bullying. It is important to point out how mobbing always brings harmful consequ-ences to the victim and their psychological state, the organisation where it happens and the envi-ronment in which that organisation operates. Sadly, even thou mobbing is becoming a more frequent phenomena in civil organisations, there are still no serious scientific and professional studies and commitment of institutions and individuals in prevention and stopping, and most of all spreading community awareness about harmful effects of mobbing on the society as a whole. Because of all of this basic education about mobbing is necessary.
